Behavioural activation (BA) is an efficacious treatment approach. Activity monitoring is a key component of brief BA treatments; however, no studies have examined the most efficacious format for monitoring. The present pilot study tested brief versus intensive activity monitoring approaches during a BA intervention administered in a college orientation course. Outcomes characterised (1) engagement with the treatment protocol via activity monitoring and (2) participant qualitative experiences with monitoring and the intervention as reported during focus group interviews. Four course sections were randomly assigned to receive monitoring forms that were brief (assessed activities three times daily) or intensive (assessed activities hourly). Forms were provided electronically to students via a web-based platform which tracked completion. There were no significant differences in monitoring frequency (38.0 vs. 23.0 days; p = .154) or the duration of monitoring engagement (62.0 vs. 36.0 days; p = .054) between the brief and intensive conditions. Qualitative findings suggested that participants in both conditions found utility in activity monitoring, particularly during the first month as they transitioned to college. Overall, findings indicated that participants may find utility in monitoring during the first month of a BA intervention using either brief or intensive monitoring forms.
